STMicroelectronics Unveils 3-Axis Gyroscope for Automotive Applications [Travel & Leisure Close - Up]
(Travel & Leisure Close - Up Via Acquire Media NewsEdge) STMicroelectronics, a global semiconductor company serving customers across the spectrum of electronics applications and a supplier of Micro-Electro-Mechanical Systems sensors and automotive ICs, has introduced a 3-axis digital-output gyroscope that meets the qualification for automotive integrated circuits.
According to a release, accurate measurements of angular-motion detection with STMicroelectronics automotive-qualified gyroscopes will enhance dead-reckoning and/or map-matching capabilities in car navigation and telematics applications. In situations when a GPS signal can't be seen, such as indoors and in urban canyons between tall buildings, dead-reckoning systems compensate for loss of satellite signal by monitoring motion, distance traveled and altitude.
ST's A3G4250D gyroscope measures angular rates up to +/-250dps (degree per second). An on-chip IC interface converts the angular- motion data into a 16-bit digital bit stream that is transmitted with high reliability to a dedicated microcontroller chip through a standard SPI or I(2)C protocol. The device provides two output lines (interrupt and data ready) and four user-selectable output data rates.
The 3V single-supply sensor integrates power-down and sleep modes and an embedded FIFO (first-in first-out) memory block for smarter power management. The A3G4250D embeds an 8-bit temperature sensor and operates within an extended temperature range from -40 to 85 degrees C.
ST's 3-axis gyroscope for automotive applications has been designed and produced using the same manufacturing-process technology that the company has already successfully applied to 1.8 billion motion sensors sold in the market. STMicroelectronics customers benefit from the combination of product design and the company's capability to manage the whole supply chain, leveraging production capacity at the company's dedicated 8-inch MEMS production lines.
